Description

Technical Field

[0001] This application relates to the field of titanium shavings cleaning technology generated during machining, and more particularly to a self-cleaning continuous titanium shavings recycling ultrasonic cleaning system. Background Technology

[0002] Ultrasonic cleaning is a technology that utilizes the cavitation effect, micro-jet impact, and vibration generated by high-frequency sound waves in liquids to achieve efficient cleaning. It has advantages such as thorough cleaning, wide applicability, and convenient operation, and its applications are extensive, including cleaning engine parts, bearings, gears, etc. in precision machinery manufacturing to remove oil stains and metal shavings; cleaning printed circuit boards (PCBs), semiconductor chips, connectors, etc. in the electronics industry to avoid electrostatic damage; cleaning surgical instruments, endoscopes, and dental tools in medical devices to meet medical-grade cleanliness requirements; and cleaning glassware, jewelry, eyeglasses, watches, tableware, etc. in laboratories and research.

[0003] Currently, in the field of machining, ultrasonic cleaning of workpieces typically involves placing the workpiece (such as long rods or pipes) in a cleaning tank, cleaning it for a certain period of time using an ultrasonic generator, and then removing it to achieve surface cleanliness. Titanium shavings generated during machining are usually recyclable and also require ultrasonic cleaning before recycling. However, titanium shavings are continuously generated during workpiece processing. While workpieces can be placed in an ultrasonic cleaning tank for a certain period, continuously generated titanium shavings require changing the cleaning water and adding cleaning solution after each cleaning cycle. This makes continuous cleaning impossible for continuously generated titanium shavings. Furthermore, the cleaning solution needs to be replaced after each cleaning cycle to remove oil stains, preventing the titanium shavings recycling and cleaning process from proceeding continuously and resulting in significant consumption of cleaning solution. Utility Model Content

[0004] To address the aforementioned problems, this application aims to provide a self-cleaning continuous titanium scrap recycling ultrasonic cleaning system, which can achieve continuous cleaning of titanium scrap and self-cleaning of the cleaning fluid, thereby improving the cleaning efficiency of titanium scrap and reducing the waste of cleaning fluid.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a self-cleaning continuous titanium scrap recycling ultrasonic cleaning system, including an ultrasonic cleaning device, the ultrasonic cleaning device having an ultrasonic cleaning tank, a plurality of oil stain nozzles arranged at intervals on the top of one side of the ultrasonic cleaning tank facing the other side, and an oil drain port opened at the top of the other side of the ultrasonic cleaning tank at the liquid level of the ultrasonic cleaning liquid, the oil stain nozzles acting on the surface of the cleaning liquid and facing the direction of the oil drain port.

[0006] A scraper is installed on one side of the ultrasonic cleaning tank. The bottom of the scraper is located at the bottom of the ultrasonic cleaning tank, and it continuously transports the impurities accumulated during ultrasonic cleaning to the outside of the ultrasonic cleaning tank.

[0007] The ultrasonic cleaning system also includes an oil stain cleaning device installed on one side of the ultrasonic cleaning tank. This oil stain cleaning device is connected to the oil drain port to achieve oil-liquid separation of the ultrasonic cleaning oil stains.

[0008] Preferably, inclined plates are symmetrically arranged in the ultrasonic cleaning tank in the direction of the oil nozzle toward the oil outlet, forming a V-shaped cleaning chamber, and the bottom of the V-shaped cleaning chamber is connected to the scraper machine.

[0009] A V-shaped rotary transmission chain plate is provided around the inclined plate, and ultrasonic generators are evenly distributed on the upper and lower sides of the transmission chain plate located in the V-shaped cleaning chamber.

[0010] The ultrasonic cleaning tank is located on the side wall of the oil drain port and has a discharge trough plate extending to the outside of the ultrasonic cleaning tank on the bottom side of the transmission chain plate.

[0011] Preferably, a first nozzle that acts upward on the transmission chain plate is provided between the discharge trough plate and the transmission chain plate, and a second nozzle that is provided at the top of the discharge trough plate and acts towards the bottom.

[0012] Preferably, a receiving mesh plate and a water receiving trough are sequentially arranged at the bottom of the transmission chain plate.

[0013] Preferably, the oil stain cleaning device includes a cleaning tank with an inlet and an outlet at both ends. The inlet is connected to the oil drain. A slag basket, an electric heating tube, an oil scraper, and an oil collection tank are arranged in sequence from the inlet to the outlet. An oil drain valve connected to the oil collection tank is provided on the side wall of the cleaning tank.

[0014] Preferably, the oil scraping device is a rotary sprocket + scraper structure, and an oil guide plate extending to the bottom of the sprocket is provided at the top of one side of the oil collection tank.

[0015] Preferably, an air flotation device is also provided at the bottom of the cleaning tank.

[0016] The beneficial effects of this application are:

[0017] 1. The oil spray nozzle can discharge the oil generated during the continuous cleaning of titanium shavings from the ultrasonic cleaning tank. At the same time, the scraper conveyor can discharge the impurities accumulated in the ultrasonic cleaning tank. Furthermore, the set transmission chain plate realizes the continuous conveying and cleaning of titanium shavings, improving the cleaning efficiency of titanium shavings. Meanwhile, the oil is discharged and the cleaning fluid is replenished in real time through the oil spray nozzle, reducing the waste of a lot of cleaning fluid.

[0018] 2. The cleaning tank can further separate the discharged oil and achieve a cleaning operation. The cleaned cleaning solution can be added back into the ultrasonic cleaning tank through the oil nozzle to achieve recycling of the cleaning solution. At the same time, the oil generated during cleaning is treated in real time, which also effectively avoids the difficulty of cleaning a large amount of oil mixture after the titanium shavings are cleaned.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] See attached document Figures 1-4 The self-cleaning continuous titanium scrap recycling ultrasonic cleaning system shown includes an ultrasonic cleaning device with an ultrasonic cleaning tank 1 and a cover plate 19 on top. This system aims to address the problem of waste caused by the need to replace the cleaning solution after multiple cleaning cycles. Figure 1As shown, multiple oil nozzles 11 are arranged at intervals on the top of one side of the ultrasonic cleaning tank 1, facing the other side. On the top of the other side of the ultrasonic cleaning tank 1, an oil drain port 1b is provided at the height of the ultrasonic cleaning fluid. The oil nozzles 11 act on the surface of the cleaning fluid and are directed towards the oil drain port 1b. Specifically, the oil nozzles 11 spray cleaning water (liquid) to the surface of the ultrasonic cleaning tank 1, driving the oil generated during cleaning and floating on the surface of the cleaning fluid towards the oil drain port 1b on the other side. This causes the oil that floats to the surface after cleaning to be discharged from the oil drain port 1b, ensuring that the cleaning fluid in the ultrasonic cleaning tank 1 remains in a clean state suitable for cleaning. Simultaneously, cleaning fluid is added through the oil nozzles 11, achieving continuous discharge of oil generated during continuous cleaning, ensuring the cleanliness and sufficient quantity of the cleaning fluid. This method is suitable for continuous cleaning of titanium scrap (continuous oil discharge) and solves the current problem of needing to replace the cleaning fluid after a single cleaning.

[0026] During the continuous oil removal process described above, the amount of titanium shavings added simultaneously increases the amount of impurities during cleaning. These impurities typically fall into the ultrasonic cleaning tank 1 and accumulate. To remove these continuously accumulating impurities and prevent their accumulation from affecting the ultrasonic cleaning space, as follows... Figure 1 , 3 As shown, a scraper conveyor 2 is installed on one side of the ultrasonic cleaning tank 1. The bottom end of the scraper conveyor 2 is located at the bottom surface of the ultrasonic cleaning tank 1, continuously conveying the impurities accumulated during ultrasonic cleaning to the outside of the ultrasonic cleaning tank 1. The scraper conveyor 2 has a structure similar to a chip conveyor in machining, with an internal rotary chain plate structure. Its bottom end extends into the bottom of the ultrasonic cleaning tank 1, discharging the continuously accumulating impurities to the outside of the ultrasonic cleaning tank 1, thus preventing the continuous accumulation of impurities inside the ultrasonic cleaning tank 1.

[0027] Since the scraper conveyor 2 is usually narrow, in order to facilitate the collection of impurities in the ultrasonic cleaning tank 1 to the scraper conveyor 2 for discharge, such as Figure 1 As shown, preferably, inclined plates 12 are symmetrically arranged in the ultrasonic cleaning tank 1 along the direction from the oil nozzle 11 toward the oil outlet 1b. The inclined plates 12 form a V-shaped cleaning chamber 1a (the bottom of the V-shaped cleaning chamber 1a, formed by the inclined plates 12 on both sides and the scraper 2, is a closed structure. Adding cleaning fluid into the V-shaped cleaning chamber 1a without completely filling the ultrasonic cleaning tank 1 effectively reduces the amount of cleaning fluid added and lowers the cleaning difficulty). The bottom of the V-shaped cleaning chamber 1a is connected to the scraper 2. The inclined plates 12 on both sides can obliquely guide and collect impurities during the cleaning process. Since the bottom ends of the inclined plates 12 on both sides are not connected, the V-shaped cleaning chamber 1a is connected to the scraper 2, allowing impurities to be collected and guided onto the scraper 2, thus achieving complete discharge of impurities outside the ultrasonic cleaning tank 1.

[0028] To achieve continuous addition and cleaning of titanium scrap, such as Figure 1 As shown, a V-shaped rotary transmission chain plate 3 is arranged around the inclined plate 12, and ultrasonic generators 4 are evenly distributed on the upper and lower sides of the transmission chain plate 3 located in the V-shaped cleaning chamber 1a. Among them, a vibrating feeder 20 is arranged on the top of the transmission chain plate 3 on the left side of the figure (the structure mainly includes the rotary transmission chain plate 3, which transfers the processed titanium chips to the transmission chain plate 3, and a vibrating motor 5 is arranged at the bottom of the feeder 20). It can vibrate the piled titanium chips added to the feeder 20 into a thin layer, and then continuously transport them to the left side of the transmission chain plate 3. Then, through the transmission of the transmission chain plate 3, the titanium chips continue to enter the cleaning fluid, and ultrasonic cleaning is performed by the ultrasonic generators 4 arranged on the upper and lower sides. The cleaned oil floats on the surface of the cleaning fluid and is discharged from the oil outlet 1b by the oil spray nozzle 11, while impurities are collected by the inclined plate 12 and discharged at the scraper 2.

[0029] To ensure the continuous discharge of cleaned titanium shavings, such as Figure 1 As shown, the ultrasonic cleaning tank 1 has a discharge trough plate 6 extending to the outside of the ultrasonic cleaning tank 1 on the side wall of the oil drain port 1b and on the bottom side of the transmission chain plate 3. The discharge trough plate 6 is preferably inclined. After the titanium chips are driven by the transmission chain plate 3 through the ultrasonic cleaning, the titanium chips are conveyed and fall onto the discharge trough plate 6. The discharge trough plate 6 is inclined and discharged outwards. The bottom of the discharge trough plate 6 is also equipped with a vibration motor 5 to facilitate the discharge of titanium chips and avoid static accumulation on the discharge trough plate 6.

[0030] After the transmission chain plate 3 rotates, some titanium shavings adhere to it and cannot fall onto the discharge chute plate 6. Figure 1 As shown, a first nozzle 71 is provided between the discharge trough plate 6 and the transmission chain plate 3, acting upward on the transmission chain plate 3. This first nozzle preferably sprays gas to blow off titanium shavings adhering to the transmission chain plate 3, and simultaneously blows some oil adhering to the transmission chain plate 3 upward into the oil layer. A second nozzle 72 is provided at the top of the discharge trough plate 6, facing towards the bottom. This second nozzle 72, under the action of the vibrating motor 5 on the discharge trough plate 6, enhances the discharge of titanium shavings from the discharge trough plate 6, and simultaneously achieves a certain drying effect through gas blowing.

[0031] The transmission chain plate 3 inevitably carries cleaning fluid with it after passing through the cleaning fluid during rotation, and this fluid will accumulate during its rotation. Therefore, in order to collect the continuously accumulating cleaning fluid, such as... Figure 1 As shown, a water receiving tank 13 is provided at the bottom of the transmission chain plate 3. The cleaning liquid adhering to the transmission chain plate 3 as it rotates from the V-shaped cleaning chamber 1a to the outside drips down into the water receiving tank 13 and is collected. A valve body can be provided on the side wall of the ultrasonic cleaning tank 1 on one side of the water receiving tank 13 to discharge excess dripping cleaning liquid accumulated in the water receiving tank 13.

[0032] Similarly, after the titanium shavings adhering to the transmission chain plate 3 are blown away by the first nozzle 71, some titanium shavings may still remain. During the rotation of the transmission chain plate 3, if... Figure 1 The shape of the transmission chain plate 3 shown causes the titanium shavings that adhere to it to fall off during the hinged rotation of each single chain plate. Therefore, a receiving mesh plate 14 is also provided on the upper part of the water receiving tank 13 to collect the titanium shavings that fall off during the rotation of the transmission chain plate 3. Similarly, a valve body or opening is provided on one side to clean out the excess titanium shavings.

[0033] To prevent the accumulation of residual titanium shavings in the V-shaped cleaning chamber 1a after prolonged use, such as... Figure 1 As shown, the corner of the preferred transmission chain plate 3 and the side wall of the ultrasonic cleaning tank 1 corresponding to the scraper machine 2 are provided with slag removal ports 1c to clean the residual titanium shavings accumulated inside.

[0034] To promptly clean the oil discharged through the oil drain 1b, the ultrasonic cleaning system of this application further includes an oil cleaning device installed on one side of the ultrasonic cleaning tank 1. This oil cleaning device is connected to the oil drain 1b to achieve oil-liquid separation during ultrasonic cleaning. The specific structure is as follows: Figure 4 As shown, the system includes a cleaning tank 8 with an inlet 81 and an outlet 82 at each end. The inlet 81 is connected to the oil drain 1b. A slag-filtering basket 9, an electric heating element 10, an oil skimmer, and an oil collection tank 15 are arranged sequentially from the inlet 81 towards the outlet 82. An oil drain valve 16 connected to the oil collection tank 15 is installed on the side wall of the cleaning tank 8. The inlet 81 is identical to the slag-filtering basket 9, allowing the mixed oil discharged from the oil drain 1b to first be discharged into the slag-filtering basket 9 for filtration of impurities and titanium filings. The filtered mixed oil then enters the cleaning tank 8 and is heated by the electric heating element 10. After heating, the oil in the mixed oil floats to the top and is scraped into the oil collection tank 15 by the oil skimmer, and then discharged through the oil drain valve 16. This ensures that the liquid discharged from the outlet 82 is clean. Preferably, a pump body can be connected to the aforementioned oil spray nozzle 11 to achieve the recycling of the cleaning solution after cleaning.

[0035] To facilitate the scraping of the floating oil sludge into the oil collection tank 15, such as Figure 4 As shown, the oil scraping device is a rotary sprocket + scraper structure. An oil guide plate 151 extending to the bottom of the sprocket is provided at the top of one side of the oil collection tank 15. During the rotation of the sprocket-driven scraper, the oil floating on the upper layer is scraped off by the oil guide plate 151 and sent to the oil collection tank 15. This can prevent the cleaning fluid from entering the oil collection tank 15 and causing a reduction in the cleaning fluid.

[0036] To further facilitate the full floating of oil stains on the surface of the cleaning solution, such as Figure 4As shown, a preferred embodiment includes an air flotation device at the bottom of the cleaning tank 8. This air flotation device comprises an air pump 17 and air flotation pipes 18 spaced apart. Air is discharged upward through the air flotation pipes 18 to achieve the air flotation effect, causing the oil and dirt contained in the cleaning fluid to float to the upper layer and be discharged, effectively improving the cleaning effect of the cleaning fluid. Impurities that accumulate in the cleaning tank 8 during the oil separation process are cleaned and discharged through the drain port 83 at its bottom.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope of protection, and all such changes and modifications fall within the scope of protection claimed by this utility model.
